Hi
Do I need to save only my Electrum seed or will my values be more secure if I also store my private keys on paper?
For example, I want to make sure my funds are still available in 5 years from now. What if Electrum by then somehow doesn't exist anymore? Can I access my wallet and funds from another provider using my Electrum seed? Or would another provider only be able to create my wallet with my existing funds if I can provide my private keys?
Sincerely, backthespace
In this case only seed is enough.
If you want look 5 years from now (hodl), you alternatively can backup all private keys that has any bitcoins in it. (this will eliminate need of keeping old copy of electrum to recover from seed)
